Definitions

  • the present invention refers to a charge air hose for motor vehicles, comprising: a hose-shaped base member and a textile reinforcement.
  • Charge air hoses with textile reinforcements are known from the prior art, wherein the textile reinforcement is embedded into an elastomer matrix or between two elastomer layers.
  • the conventional textile-reinforced charge air hoses are exposed to great mechanical work when being dynamically stressed. Both components, the reinforcement and the matrix embedding the reinforcement have different stress-strain characteristics. If the reinforcement is positioned between two layers, shear forces at the joint of matrix/reinforcement are produced when the hose is loaded, which lead to delamination of the composite and which can thus lead to failure. Additionally, microcracks in the adjoining elastomer matrix may occur as a result of the dynamic-mechanical load (strain caused by the expansion of the hose and superimposed coercive movements) due to the notch effect of the reinforcement (high e-module compared to the elastomer). These microcracks must be regarded as an origin for a crack growth.
  • the invention is based on the object of solving the problems known from the prior art, and particularly to provide a charge air hose which has a significantly prolonged life compared to the conventional hose when being dynamically loaded.
  • the invention provides a charge air hose for motor vehicles comprising: a hose-shaped base member, a textile reinforcement arranged on the surface of the base member, wherein the hose-like base member is a vulcanized, elastomer-containing hose. Since the reinforcement is arranged on the hose surface, the charge air hose according to the invention comprises one single joint between the base member and the reinforcement. The reinforcement is applied onto an elastomer in non-vulcanized state during a conventional manufacturing process and is covered by at least one elastomer layer. Due to the non-vulcanized state the elastomer is soft.
  • the reinforcement penetrates the elastomer surface.
  • the contact surface between the elastomer and the reinforcement is therefore three-dimensional.
  • the elastomer enclosed the yarns of the reinforcement.
  • the positive connection has a very low bearing strength and is a weak point also when the hose is loaded to a small extent only, wherein the reinforcement disengages from the elastomer.
  • the textile reinforcement is applied onto a pre-vulcanized, elastomer-containing hose.
  • the elastomer-containing hose was preferably vulcanized before applying the textile reinforcement. This reduces friction of the textile reinforcement with respect to the elastomer hose in the case of dynamic load.
  • the elastomer-containing hose is hard in the vulcanized state and the reinforcement can therefore not penetrate into the elastomer-containing material.
  • the contact surface between the reinforcement and the elastomer-containing material is the two-dimensional surface of the elastomer-containing hose.
  • the power transmission from the hose surface to the reinforcement is predominantly positive (at right angles to the hose surface) and in the ideal case it is therefore frictionless.
  • the charge air hose according to the invention is, compared to the conventional charge air hose, very suitable against dynamic fatigue.
  • At least one pressure ring is arranged above the textile reinforcement. This has the advantage that the pressure ring holds the reinforcement tight to the contour of the base member.
  • the hose-shaped base member is formed as an elastomer hose.
  • the elastomer-containing hose has a substantially smooth surface. This measure reduces friction between the reinforcement and the base member, which increases life of the charge air hose according to the invention when being loaded dynamically.
  • the elastomer-containing hose is manufactured by an extrusion or injection molding process. These manufacturing methods prove to be especially economical in connection with elastomer-containing hoses.
  • the elastomer-containing hose has a thermoplastic elastomer.
  • a thermoplastic elastomer By the addition of a thermoplastic elastomer the dynamical and mechanical properties of the hose can specifically be adjusted.
  • the textile reinforcement is formed as a knitted fabric or as a braid.
  • the reinforcement can be designed such that it rests properly on the elastomer-containing hose and that its deformation does not exceed the range of its structural expansion. The reinforcement is therefore in a lower tension state than is the case with the conventional charge air hose, which above that is regular across the entire hose surface.
  • Structural and material expansion are the two classical elastic expansion states of a textile structure. A textile structure is deformed by very low forces in the area of the structural expansion. The reason for this is that the yarns can slide against one another in a predetermined manner depending on the textile structure (knitted fabric, braid) and the textile structure can therefore adopt other shapes without the yarns being loaded mechanically.
  • the fineness or strength of the yarn is freely selectable according to the respective requirement profile, since compared to an internal reinforcement as in a conventional charge air hose there is no interaction (notch effect) between the reinforcement and the matrix.
  • the adhesion between the layers additionally plays an essential role. In so far the strength of the yarn is limited. The stronger the yarn the worse the layer bond in the original state.
  • the reinforcement can be applied by a form-fitting weaving-around operation, which is particularly suitable for smooth hoses.
  • the application of a pre-fabricated braid or knitted fabric (e.g. a pre-fabricated braid hose) proves to be an option and is particularly suitable for corrugated hoses.
  • the textile reinforcement is made of glass filament.
  • Glass filaments belong to the high-strength yarn materials, they are inexpensive and are characterized by high thermal and chemical resistance and by a very low expansibility.
  • the textile reinforcement is formed as a 3D-braid.
  • This manufacturing method of the textile reinforcement enables an especially high adaptation to the shape of the base member and thus an especially low relative movement of the textile reinforcement towards the base member when the charge air hose according to the invention is dynamically loaded.
  • the textile reinforcement surrounds the molded hose properly.
  • the textile reinforcement is impregnated and/or coated by a coating material. This protects the reinforcement against wear, e.g. caused by friction. Furthermore, the yarn or the textile reinforcement are provided in a cut-proof manner and are thereby protected against fraying of the individual filaments. Furthermore, the impregnation or coating of the reinforcement serves for fixing on the hose surface or for assembly adhesion. Furthermore, the yarn filaments are protected in view of the connection (e.g. to a charge air tube by means of hose clamps, couplings etc). In this embodiment, the later impregnation is possible with contour-close surfaces as well as the direct coating of the textile reinforcement after the braiding process in pre-fabricated braided hoses.
  • the yarn of the textile reinforcement is provided with an impregnation.
  • the impregnation is applied preferably prior to manufacture of the textile reinforcement, i.e. before braiding or knitting. This measure also serves for protecting the yarn and the textile reinforcement against wear. This protection is especially important at the yarn intersecting points of the textile reinforcement which are a weak point with respect to yarn/yarn friction.
  • the coating material is a resin or an elastomer, preferably a silicone elastomer.
  • the flexible resin or elastomeric coating e.g. in the form of solutions or lattices is a suitable material.
  • an adhesion-modified silicon elastomer is used as coating material, by means of which a universal temperature resistance, high flexibility and favorable adhesion to the glass fiber filaments can be achieved.
  • the coating material is applied by submersion, varnishing or coating of the charge air hose, or by extrusion when braided hoses with later crosslinking are used, since the elastomeric coating material must fundamentally be vulcanized after application, preferably by an online method.
  • the coating material is dyed in a color different compared to the base member and/or the reinforcement. This enables an identification of the charge air hose by the coating.
  • the textile reinforcement is embedded on at least one hose end into a material adhesively joined with the base member.
  • the charge air hose is preferably coated at the hose end. This prevents a detachment or fraying of the textile reinforcement and serves for functionalizing the hose ends in view of the connection and integration of functions, e.g. in the clamp seat, clamp fixing, installation marking, etc.
  • a cap preferably an elastomeric cap is adhered and/or vulcanized onto at least one hose end.
  • Functionalized elastomeric hose sections are suitable for being adhered or vulcanized onto the hose ends.
  • a further preferred embodiment of the invention refers to a method of manufacturing a charge air hose for motor vehicles, comprising the following steps: providing an elastomer-containing hose as a hose-shaped base member, vulcanizing the elastomer-containing hose and applying a textile reinforcement onto the surface of the vulcanized, elastomer-containing hose.
  • a further preferred embodiment of the method according to the invention comprises the impregnation and/or coating of the textile reinforcement by a coating material to reduce the wear of the textile reinforcement.
  • a further preferred embodiment of the method according to the invention comprises the impregnation of the yarn of the textile reinforcement with the aim of reducing wear of the textile reinforcement by reducing the yarn/yarn friction at the intersecting points of the textile reinforcement.
